🎥 End-to-End YouTube Video Automation Workflow with n8n, HeyGen & AI

🧠 What problem does it solve?

Publishing consistent, high-quality video content is essential for audience growth and monetization. But manually creating each video — researching, writing, recording, uploading, and optimizing — is slow, repetitive, and unsustainable at scale.

This workflow solves that by automating:

✅ Content sourcing from Google Sheets
✅ Script generation with AI
✅ Avatar video creation via HeyGen
✅ YouTube upload and metadata
✅ Final publishing and status update

All done without touching a single button. Schedule it weekly and watch videos go live while you sleep.
